Oxyacetylene Spray Welding

The oxyacetylene flame spray welding process is to heat the alloy powder through an oxyacetylene flame until it melts or reaches a plastic state, and then sprays and deposits it onto the surface of the treated workpiece, thereby obtaining wear resistance, corrosion resistance, and high temperature oxidation resistance on the surface of the metal substrate. Welding layer with special properties.

Kennametal Stellite produces a variety of alloy powders suitable for oxyacetylene flame spray welding processes, and can provide various mixed powders according to user conditions to meet harsh usage conditions. With decades of experience in the application of oxyacetylene flame spray welding processes, we can provide customers with one-stop solutions from cladding material selection to process development.

The oxyacetylene spray welding process has a metallurgical bonding state between the clad metal and the base material, with high bonding strength, low dilution rate of the welding layer, and very high straightness of the fusion line. The hardness of the welding layer can be determined according to the selected alloy powder to be within HRC20 - HRC62 is freely selectable, and the welding layer thickness can also be freely controlled within 0.15-3mm.
